Study Notes
Hierarchy and Structure in Conceptual Representations
- Conceptual representations follow a hierarchical structure with three levels: subordinate, basic, and superordinate.
- Basic level categories are the most useful due to their balance of informativeness and distinctiveness.
- The basic level in a taxonomy is where categories carry the most information and are most differentiated from each other.
- Research by Rosch, Mervis, Gray, Johnson & Boyes-Braem in 1976 showed that very few features were generated for superordinate categories, while most features were at the basic and subordinate levels.
- Participants in the study by Rosch et al. generated 1595 basic level names, 14 subordinate level names, and 1 superordinate level name for objects.
- The utility of category abstraction varies based on expertise, as demonstrated by Tanaka and Taylor's comparison of naming patterns of dog experts and bird experts.
- Efficient thinking requires choosing the right level of abstraction, as seen in the examples of naming objects.
- Hierarchical organization optimizes cognitive economy by allowing for inferences based on category relationships.
- Conceptual representations have graded category structure, influenced by inter-item similarity relationships and contrast categories.
- The existence of contrast category effects has seen little empirical support, with studies like Verbeemen et al. (2001) finding few significant correlations.
- Dry & Storms (2011) argued that models not accounting for distinctive feature information led to the failure to find contrast category effects.
- When distinctive feature information was considered, significant evidence of contrast category effects was found in the prediction of typicality gradients for categories within the domains of animals and artifacts.
